  • DPP designs and manufactures custom pumps to fulfill your OEM equipment requirements.

  • DPP tests at your operating conditions. This ensures that the pump performs to expectation before you validate in your equipment. We are also capable of conducting long-term endurance testing, environmental and chemical compatibility testing.

  • No. Every pump is designed and tailored to our customer’s exact needs. We have a minimum volume requirement of 100 pieces/year.

  • The customer provides DPP with the performance requirements via an Application Data Sheet (ADS). DPP uses this information to size the pump, design the interfaces and set up the test/validation program.
